ToALL WHoM 1r MAY coNoEnN:

Be it known that I, FREDERICK Loos, of Germantown', in the county of Philadelphia, and State of'Penn-sylf t in Self-Fastening Buttons; and I do hereby declare that the following is a full, clear, `and and use the same, reference beinghad'to the accompanying drawings, forming part of this specification.

My invention relates to an improvement inv Athat class of buttons whic v material without requiring to be sewed thereto, and, therefore, technically called `self-fastening-buttons 'My invention consists in the combination, with'al screw-'socket secured to the bac a anged end, and serrated around the edge,- of`ascrewpin, having 'a head suiciently large to prevent the. cloth tearing at the point Wherethe'said pin passes through it, whereby the button is secuelynttached tothe material, and in a manner which will prevent the cloth and ulrich, at the same time, can beeasily'applied and vwithdrawn Without iu the'least injuring the materialen which it is used. Iii the accompunyingdran'i'ngs- Figure 1- is a longitudinal section of my invention, when appliedto apiece of cloth.`

Figure 2 is an inverted vieir oi the button detached from the cloth, showing the screw-socket providedl fori Figure 3 is an enlarged view ofthe screw-pin.` y

Figure 4 is 'a sectional riew', showing Vmy,invention applied to a cloth-covered button.l

Figure 5 is also a, sectional View, showing the-same applied -to another-stylel of metal button.

Similar letters of reference indicate like* par-ts. l

The invention may be applied to any kind of button new in the market. y

A, inthe several figures, designates the body of the button, B, in any suitable manner, which socket has formed around its outer end a flange, afwhich, inthe present instance, is rounded or bent, so that its sides are upward, and its-edges are toothed.or serrated, so as to enable itto .take 'a better hold uponthe material, as well as to p screw-pin, which is tted to lscrew into the socket IB.v This screw-pin' carries a head, 11, suiiiciently large to clamp the material for a proper distance around the hole through which the pin passes, topreveut the same from tearing' in any way. lThe said head has a slot, c, cut in it, like a screw,'to perrnit it to .he .screwed into and out of the socket .with the aid of a penknife,'or`anything with va thinedge. 'These two parts'B and C, incombination with each other, constitute my'fastening. This fastening will i be attached. The screw-pin is sosmall'thatvit leayes no perceptible hole in the garment; therefore it can he applied to `studs for fastening shirt bosomsand sleeves,`&c., &c.', withoutinjuring the material; and the vfacility with which the s tud may be applied, 'and the rapid manner in which it may be secured, recommends the fastening for such use. A, It is securejin every respect.V

AWhat I claim as new', andv desire to secure by Letters Patent, is y The combination of the screw C, concave-convex disk b, vand serrated shank B a; the saidserrated shank and disk being of unequal diameter, all substantially as` described, for the purpose set forth.
